The advantage is that it needs less cable and minor bending of cable resulting in
higher cable duration. There is annother system is this, i don´t have found a better
image. If you need ask and i make a illustrationhttp://www.practicalmachinist.com/vb...shed-table.jpg
Basically is a L shaped cable holder, or a stright one and some rope from ceiling or
ceiling rood.

Darren I think that would be alright. My company, unfortunately, runs the torch lead inside the cable carrier along with the shielded motor cables. 9 out of 10 times on installs it doesn't effect with emi. I am still trying to win over the engineers on separating the torch lead differently. For now I am having them zip tie the lead to the outside of the cable carrier. Baby steps I guess.

The main thing to watch out for is the location of your power supply to your cables and computer. Also don't coil the work clamp up like when coiling up a extension cord. It creates a quite a problem so uncoil the work lead.

Hope that helps a little. Of course proper grounding is a big thing and I'm sure you know about earth grounds and star grounds.

Star ground is directly grounding each item to a single ground point. It helps prevent ground loops, and keeps the route to ground direct for each device rather than 'daisy chaining' through connections where other devicdes might have a 'shorter distance to ground' electrically.

Basically, ground everything using insulated grounding straps (big wire) all going to a single ground point is electrically a more sound arrangement for the 'just in case' issues none of us want to happen anyway (and don't happen in a 'perfect world').

Hope that helps. Someone else with more experience might have a better explaination, but this works for me.
